With a zero annual floor, at a 20 year average all-in expense ratio under 1%, and a 90% leveragability at net zero cost (and actually often a positive credit arbitrage,)... nobody's brought forth anything that can outperform.

It doesn't always outperform accounts with deper loss tolerances... but if you want more risk in order to chase more profits, the liquidity lets you do it on a smart selection basis, rather than being forced to "weather it out" during drawdowns.

I have no idea what "90% leveragability" means -- but it sounds suspiciously like going to 90% margin in your retirement account. Not something to boast about, IHMO.
